A magnetic head apparatus for a magneto-optical recording medium recording and/or reproducing apparatus includes a head body and an arm-shaped support mechanism. The head body includes a magnetic head unit for generating perpendicular magnetic field, and a contact-slide portion to which the magnetic head unit is secured and which is slid along the magneto-optical recording medium in contact with the surface of the magneto-optical recording medium. The arm support mechanism to which the head body is secured is movable in such a direction that the magnetic head unit is contacted with or away from the magneto-optical recording medium.The arm-shaped support mechanism has an arm portion, a fixed portion and first and second elastic displacing portions. The head body is secured to one end side of the arm portion through the first elastic displacing portion. The fixed portion has one end secured to the fixed member and the other end which is linked to the other end of the arm portion through the second elastic displacing portion. The arm-shaped support mechanism is disposed so as to sandwich the central axial line of the support mechanism, and it comprises a pair of plate-shaped elastic members constituting the first and second elastic displacing portions, and a resin portion which is provided at both sides of at least one of the elastic members and forms the arm portion and the fixed portion.
